ELECTRIC-SIGNAL RECORDER.

SPECIFICATION forming part of Letters Patent No. 339,381, dated April 6, 1886.

Serial No. 183,865. (No model.)

To aZZ whom it may concern:

Be it known that I, ANDREW J. COFFEE, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved ElectrieSignal Recorder, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in the devices for giving fire-alarm signals; and the object of my invention is to provide a new and improved device for recording the signals by ink impressions tion of my improved electric-signal recorder.

Fig. 2 is a sectional plan view of the same.

The electro-magnet A is in the signal-line, and its armature Bis secured to one end of the lever G, fulcrumed at D. A spring, D, draws the end of the lever O upward when it is released, and a checkscrew, D", limits the upward movement of the said lever. From one side of the lever O, at the end opposite the one carrying the armature, two pins or studs, E E, project, which are short distances from each other on an inclined line, and have curved or convex backs. Alike pin or stud, F, projects from one side of the arm G of a wheel, G, toward thelever O, the said wheel G being revolved bya clock-work mechanism, II, having the flier H. The pins I and J'project from the side of the wheel G, of which the pin J projects into the longitudinal slot K on the lower end of the lever K, pivoted at K and having its upper end pivoted to the lever L, from one end of which the impression-block M, of rubber or other suitable material, projects downward. The opposite end of the lever L is provided with the transverse pin N, which passcsinto the slots l in side pieces, N", the said slots having their end parts extending upward from each other in the manner shown. The inking-pad O is placed below the impression block M, and contains several pieces of thick fabric, felt, &c., saturated with stamping-ink of any well-known kind. The strip P, of paper, is wound on the reel P, is passed over the roller Q in front of the inking-pad 0, over the platform Q, over the two rollers It and S, and is secured in the empty take-up reel T, which, with the reel P, is j ournaled in hangers projecting from the platform Q. The reel T is provided with a spring which revolves it to take up the slack of paper in the same manner that the slack of a window-shade is taken up by the spring shaderoller. The rollers It and S are mounted in a frame, R,and springs R in the same, press the roller S against the roller R. The roller R is connected with the pinion U, which is revolved by the cog-wheel U, driven by the additional clock-work V,which runs synclno nouslyfwith the clock-work H. The clock work V is locked by a rod, \Y, which can be acted on by a rod, \V, extending to the clockwork H, and is provided with a downward bend, II, on which the pin I can act. The inking-pad O can be adjusted higher or lower, so that theinking-block M can easily rest on it.

The operation is as follows: When the circuit is broken to give a signal/the armature B is released from the magnet and is drawn up by the spring 1), whereby that end of the lever 0 provided with the studs E and E is moved downward. The pin Eis thus moved downward and disengaged from the stud F, whereby the wheel G is released and is revolved by the clock-work in the direction indicated by its arrow. The lower end of the lever K is moved by the pin J in the direction of the arrow a and the upper end of the lever K, and with it the lever L, is moved in the inverse direction of the arrow a. The end levels of the slots N, acting on the pin N, depress one end of the lever L, and thereby the end carrying the block M: is raised, and when said block is above the roller Q, the pin N arrives at the other bevel of the slot, the marking-block M is moved down by the action of the bevels of the slots on the pin N, and an impression is made on that part of the paper strip on the roller Q. hen the wheel G completes its revolution,the lever K is swung backward and the lever L and the printing-block M are brought back to their original position. XVhen the pin I strikes the bend IV of the wire W, the said wireW is moved in the direction of the arrow 1), and thereby the clockwork V is released and revolves the rollers R S, whereby the paper-strip P is unwound by said rollers from the reel P, the slack part of the strip being wound on the reel T. When the wheel G has made a complete revolution, its pin or stud F strikes the pin or stud E and is thus locked.

When the circuit is closed, the end of the lever C is swung up and the stud 01' pin F slides oif the pin E and catches on the pin or stud E.

The operation is repeated the next time the circuit is broken, and thus an impression is made for each break in the circuit, and the signals given are automatically recorded on the strip P.

The clock-work V is stopped automatically by the rod WV, which is pushed down by a pin, m, on the cog-wheel U coming in contact with said rod W when the said wheel U has made a complete revolution. The lower end of the rod W comes in contact with a pin, 0, on the small cog-wheel geared to the flier, and thus stops the clock-work. The spring a on the rod WV actuates the same upward, when the said rod W" is pushed away from the pin m by the rod W, and the spring I) on the rod XV holds the same in its normal position.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a clock-work, of an electro-magnet for releasing it, a printinglever operated by the clock-work, an additional clock-work for feeding a strip of paper on which the impressions are made by the printing-lever, and of a rod for releasing the paper-shifting clock-work from the clock-work operating the printing device, substantially as herein shown and described.

2. The combination, with a clock-work, of a printing device operated by the same, an additional clock-work for feeding the paper on which the impressions are made, a reel containing the strip of paper, and a spring-reel on which the paper is wound, substantially as herein shown and described.

3. The combination, with a clock-work, of the wheel G, operated by it, the pivoted lever K, acted on by the wheel G, the lever L, pivoted to the'upper end of the lever K, the printing-block M on one end of the lever L, the pin N on the opposite end of the lever L, and the plates N having the slots N, the ends of which are inclined upward from each other, substantially as herein shown and described.

4. The combination, with a clock-work, of the wheel G, operated by it, the lever K, operated by the wheel G, the lever L, pivoted to the upper end of the lever K, and mounted to swing and movein the direction of its length, and of the printing-block M and ink-pad O, substantially as herein shown and described.

5. The combination, with a clock-work, of the wheel G, operated by the clock-work, the lever K, operated by the wheel G, the lever L, pivoted to the lever K, the printing-block M on the lever L, the inking-pad O, and the roller Q, over which the paper on which the impressions are to be made is passed, substantially as herein shown and described.

6. The combination, with a clock-work, of the wheel G, provided with the pins or studs E E, the electro-magnet A, the lever 0, carrying the armature B, the stud or pin 1? on the lever O, the lever K, operated by the wheel G, the lever L, pivoted to the upper end of the lever K, and of a printing-block on the said lever L, substantially as herein shown and described.

7. The combinatiomwith a clock-work mechanism, of the wheel G, provided with the pin I, a printing mechanism operated by the wheel G, an electro-magnet for releasing the said clock-work mechanism, the additional clockwork mechanism V, for feeding a strip of paper, and the rod W, for releasing the clockwork mechanism, on which rod W the pin I acts, substantially as herein shown and described.

8. The combination,with a clock-work mechanism, of the wheel G, operated by the same, a printing mechanism operated by the wheel G, an electro-magnet for releasing the clockwork mechanism, the paper-reels Pand T, the rollers Q, R, and S, and an additional clockwork mechanism for revolving the roller R, I00

substantially as herein shown and described.
